Application filed October 15, 1907. Serial No. 397,534.

. .To all whom it may concern.

Be it known that I, THEODORE FALKOV- SKY, subject of the Emperor of Russia, residing at St. Petersbur Russia, have invented new and usefu Improvements in th'a t their arran ement is com' aratively complicated and t at, in course o time, the

" eteriorated.

The extinguisher which constitutes the :--storing.

. pipes 9 for the escape of'the liquid and the -"arts that bring about the action become present invention is of a very simple construction and'of quite sure action during an indefinite length of timereven under the most unfavorable conditions with regard to The accompanying drawing showsa vertical section of the apparatus;

This apparatus consists of an external receptacle 1 of'any suitable shape provided at the bottom with an opening, which is closed by a stopper 8 of cork or any other light' material, t e said receptacle being connected with a chamber provided with perforated gases that are formed when the apparatus is gas developed in the receptacle 1 when the caused to operate. l

19 denotes a basket to receive the stopper 8 which is driven out by the pressure of the apparatus is made to operate. A second receptacle 2'is arranged in thereceptacle 1; it possesses double walls between which the acid is placed, and a 'doublebottom 6 & 7 of lass. the space. between the inner wal s of the receptacle 2, there is a pin 5 which is intended to bi zak the glass panes 6 and 7 of-the bottom and a weight 3 siig pended in a special frame 10 by means of a" all ,4 which is easily melted. When the emperature is thus raised so as to cause the fusion of the ball 4, the weight 3 falls down and strikes the pin 5 which breaks the glasses 6 & 7 and consequently the acid contained in the receptacle 2 flows into the alkali contained in the receptacle 1. The gases which develop in the latter drive out the stopper 8, whereupon theliquid saturatedwith. gas is distributed in the pipes 9 and escapes through the holes of the latter, thus'causing the fire to be extinguished.

A contact for an alarm bell may be ar-.

ranged on the upper part of the frame 10;

said contact consists of a metallic lever 11 provided with a balance-weight 12 and pivoted on an insulated rod 13. The end of the lever 11 is fastened to the frame 10 by means of a cord or-a thin string 14 of fusible material. When a conflagration is producedthe string 14 breaks or tears owing to the action of the heat or fire and "the wei ht causes the opposite end of the lever 11 to all down,'whereby contact is produced and the electric alarm-bell 15 is made to operate.

I'claim. 1. In a chemical fire extinguisher, the combination with a tank, of a container mounted therein having double walls form ing an inner conduit open at the top and an annular acid chamber, fragile closin mem-' bers in the bottoms of the conduit an chamber, a weight in the conduit, a support above the latter, and a fusible support normally connecting the weight to the support.

2. In a chemical fire extinguisher, the combination with a tank, of a container mounted therein having double walls forming an inner conduit and an annular acid chamber, fragile bottomsin the conduit and chamber, a support above the conduit, a weight in the latter, a fusible member onthe support normally holding the weight above the bottom, a removable stoppermounted in an a erture'in the bottom of the tank, and per orated distributing pipes communicating with the tank through the aperture.

In testimony whereof, I have signed my name to this specification in the presence of .two subscribing witnesses. I
